“Being fractal is a way for a system to be in touch with itself, talking to itself, but not locked in,” Goldberger says. “You can’t exist if you’re fixed at one frequency, but if you’re all over the place, that also doesn’t fly."

Very reminiscent of Daniel Siegels' complexity science based definition of "mental health". Whereas he believes "a human being is a complex system, striving to complexity", mental health can be defined as a "self-organized process that enables a person, or a relationship or a group to continually move toward maximal complexity. Unresolved trauma creates impairment to this striving and leads to either chaos or rigidity".
